HIGH QUALITY MATERIALThe folding van bag is made of 600D wear-resistant, tear-resistant Oxford cloth material on the outside, and the interior is made of environmentally friendly high-quality aluminum film that is easy to clean and insulated with EPE cotton, which allows for optimal insulation (because the van stowage bag is made of nylon with sewn-in stitching holes, so the low-temperature food will seep in when it goes into the van bag)
